Triple-warped supernova in JWST photo provides hope that one of the universe’s biggest problems can be fixed


The distant supernova “H0pe” can be seen three times (labeled SN2a, SN2b and SN2c) in the orange arc of light surrounding a galaxy cluster on the left side of this James Webb Space Telescope image. Other gravitationally-lensed objects are also labeled in this image.  (Image credit: B. Frye et al., ApJ submitted, 2023)

A rare, warped supernova that appears three times in a single image could help researchers finally solve a long-standing inconsistency about the universe that has threatened to unravel our understanding of the cosmos, one expert claims. 

The type 1a supernova, named SN H0pe, was first discovered lurking in photographs captured by NASA’s James Webb Space Telescope (JWST) in March. In these images, the exploding star can be seen as an arc of orange light with three bright points that surround part of the galaxy cluster PLCK G165.7+67.0 (G165), which is around 4.5 billion light-years from Earth.
